The invention aims at an arrangement for sliding Windows. Usually one of the two halves of a window is fixed and the other is slidable and this arrangement has the object of pressing the slidable half window tightly and without drag against the grooves in the fixed window frames. The slidable half window in the closed position is mainly in the same plane as the other fixed half window.

The essential feature of the invention is that the slidable half window is provided at its opposite ends with rotatable axles, arranged mainly vertical to the direction of movement, on which. are mounted cranks engaging in corresponding guide grooves in the fixed window frame, and these axles so coupled that they are forced to rotate simultaneously by means of a handle fixed to one of the axles,

By this means the slidable half window is carried out from the crank pin in such a way that the half window swings from its closed position in the window frame mainly parallel to itself into a free position and in this position the window can be slid behind the fixed window half. In this way the thickness of the whole window need not exceed the thickness of a single half window (or the thickness of two coupled window arches), which for aesthetic reasons is of great importance. In addition the slidable window half in its closed position can be pressed firmly in the grooves by means of the coupled levers.

One form of the invention applied to a vertically slidable window is illustrated in the accompanying drawings:

Fig. 1 shows one half of the window in horizontal section.

Figs. 2 and 4 show the window in vertical section with the slidable window half in closed and opened position.

Fig. 3 shows a variable fastening device.

Fig. 5 shows a vertical section on V--V of Fig. 6, agreeing with Fig, 2.

Fig. 6 shows an elevation of the crank system, etc.

In the drawings i indicates the fixed frame, 2 the fixed half window and 3 the slidable part or sliding window. At the upper and lower ends the sliding window is provided with rotatable axles 4 and 5, arranged transversely to the direction of movement, having angle cranks 6 which a crank arm on the one axle couples, by means of a rod 1 with an opposite corresponding crank arm or similar device with an eccentric effect on the other axle, so that a rotation of one axle simultaneously causes the rotation of the other axle in exactly the same way. The rods 1 are provided with a screw thread l5 or the angle cranks are spring mounted accordingly to Fig. 3. The other arms of the single angle cranks 8 are provided with pins 8, which engage in corresponding guide grooves 9 in the fixed frame, and at the lower end the guide grooves are provided with stops it], which limit the downward movement. Preferably at the middle of the axle 5 there is arrangeda hand grip ii upon a support 12, which part is actuated by hand, is arranged as a lever, whose one arm has various supports (fixed points) against a lock l3 secured on the slidable window half by a screw M, by which the handgrip allows itself to shut in various positions by means of this lever. The lever of the handgrip is so ar ranged that different closings of the window occur automatically.

In the closed position (Fig. 2) the sliding window can be pressed firmly against corresponding grooves in the fixed frame through the influence of the handgrip H and is then mainly in the same plane as the fixed half window 2. If the window is to be opened the handgrip II is grasped, which allows itself to be rotated to a position as shown in Fig. 4 and the sliding half window 3 swings during the rotation about the crank pins 8 approximately to a position inside the fixed half window and the sliding window half can then easily be slid up and is guided by the crank pins 8 in the grooves 9. In order to stop the half window at a desired position of the sliding, the half window is counter-balanced by weights.

I claim:

1. In combination with a sliding window, a rotatable axle transversely mounted on the upper and lower end thereof, a crank fixed to the respective ends of said axles, an adjustable connecting link between the cranks at the ends of the upper and lower axle, a guide pin integral with each crank, a guide fixed to each side of the window frame engaged by said pins integral with the cranks on each side of said sliding window, a hand grip connected to the lower axle and means co-operating with said hand grip actuating said sliding window when moved in one direction and when moved in the opposite direction locking said sliding window in any desired. position.

2. In combination with a sliding window, a rotatable axle transversely mounted on the upper and lower end thereof, a crank fixed to the respective ends of said axles, an adjustable connecting link between the cranks at the ends of the upper and lower axle, a guide pin integral with each crank, a guide fixed to each side of the window frame engaged by said pins integral with the cranks on each side of said sliding window guiding the window during its movement, a stop at the end of each guide limiting the downward movement of the sliding window, a hand grip connected to a lower axle actuating the sliding window, a guide rail of approximately triangular shape fixed to the sliding window at each end of said hand grip and a stud at each end of the hand grip engaging with the respective guide rails, said sliding window actuated on the upward swing of the hand grip and on the downward swing of the hand grip said sliding window is locked in any desired position.
